Tamar Island has been Crown Land since settlement and up to the 1980s was leased to private and public operators. In the 1980s the Tasmanian Government purchased the wetlands area around Tamar Island, which was incorporated into the greater Tamar River Conservation Area.
Wetlands play an important role in maintaining water quality. They also provide important habitat for many native animals and plants, with many species relying on wetlands as places to feed and breed.
An interpretation centre offers visitors the opportunity to learn about the value of the wetlands.
The Tamar Island Wetlands is managed by the Tasmania Parks and Wildlife Service, with significant assistance from Wildcare volunteers who operate the centre and provide visitor services year round.
